Battery testing has become a very critical task nowadays. All kinds of battery testing equipment are slowly put into application with the development of science and technology. So what are the testing items for power battery testing equipment? Let me introduce it to you.

1. Voltage: The test equipment checks the voltage twice, one is the full-load voltage, and the other is the voltage after all items are tested, especially after the short-term warranty, to ensure that the battery is all normal after the short-term warranty, so the two voltages are somewhat different. Yes, the secondary voltage is a little smaller than the primary voltage.

2. Internal resistance: It detects the 1000hz communication internal resistance of the battery,

3. Charging overload protection current: First of all, it is necessary to determine whether the battery has a charging current that is too large, and the automatic maintenance function. If the charging current is very large, the battery has no maintenance function, and it is very easy to burn the maintenance pcb circuit board in the battery. Therefore, it is very important to ensure that the battery has a charging overload protection current function. If not, select the continuous charging current.

4. Continuous charging current: For the pcb circuit board that does not have a large charging current for automatic maintenance, such a battery generally selects the same current value as the charger under charging.

5. Charge and discharge overload protection current: After the charge and discharge current exceeds a certain standard value, automatic maintenance, generally according to the basic parameters of the manual.

6. Continuous charging and discharging current: It refers to the charging and discharging current of the battery under normal application conditions. If there is any problem with the pcb circuit board, it will cause a situation where it cannot be continuously charged and discharged.

7. Overcurrent protection time: In the case of an instant short-circuit fault of the positive and negative of the battery, the lithium battery protection board closes the reflection time, because the short-circuit fault instantaneous current is very large, if the reflection time is too slow, it is very easy to cause the pcb circuit board to burn. Therefore, the faster the time, the higher the maintenance of the battery, generally below 1000us. If the internal resistance of all control loops is too large in the case of a short-circuit fault, the short-circuit fault time will be too long, and the short-circuit fault will be too large. In this case, special attention should be paid to the analysis of what is going on.

The above is the basic test content of the power battery test equipment. In the process of using it, you should also understand what you need to use the power battery test equipment to do.
